The Investigation of Relationship between Anthropometrical and Physiological Parameters of Elite Young Boys in Breaststroke and Butterfly Swimming

Background: The relationship between anthropometrical and physiological parameters of elite young boys in breaststroke and butterfly swimming is essential. We aimed to investigate the relationship between anthropometrical and physiological characteristics with breaststroke and butterfly swimming time in elite swimmer boys. Materials and Methods: This study was a descriptive research, comprised of 122 elite young boy swimmers (age 12-13 years; height 1.540±8.24 m; weight 47.820±6.84 kg), who participated in the national championship of the country’s selection in 2018 in Shiraz, Iran, and who had signed the consent form Anthropometrical and physiological parameters were measured for 5 days. Pearson correlation coefficient was used to examine the relationships between variables. Results: There were significant negative relationships between supraspinatus fat (r=-0.461, P=0.009), right leg strength (r=-0.376, P=0.037), and static balance (r=-0.629, P=0.0001) with 50 m breaststroke time, between leg power (jump length)(r=0.448, P=0.015), and static balance (r=-0.529, P=0.003) with 100 m breaststroke time, between head circumference (r=-0.472, P=0.023), and leg power (jump length)(r=-0.454, P=0.030) with 200 m breaststroke time, between subscapularis fat (r=-0.434, P=0.012), and trunk flexibility (r=-0.350, P=0.046) with 50 m butterfly time, between trunk flexibility (r=-0.445, P=0.029), and100 m butterfly time. Whereas, there were significant positive relationships between leg action and reaction velocity (r=0.411, P=0.013) with 50 m breaststroke time, between dynamic balance (Internal)(r=0.368, P=0.050), and 100 m breaststroke time, between leg power (jump length)(r=0.511, P=0.002), and 50 m butterfly time, between triceps fat (r=0.489, P=0.015), and subscapularis fat (r=0.561, P=0.004), and dynamic balance (lateral)(r=0.424, P=0.039) with 100 m butterfly time. Conclusion: There was a significant relationship between anthropometrical and physiological characteristics with elite young boys in breaststroke and butterfly time.
